Abstract
A recording medium has a first recording area on which multiplexed audio informations are recorded as sets of one or more information units, a second recording area on which control information for controlling recording of the multiplexed audio informations are recorded. The control informations include first information representing the number of sets of information composing the multiplexed audio informations, and second information instructing to record the multiplexed audio informations as a stream.
Claims60
A disc-shaped recording medium comprising:
- a video data recording area in which video data and an audio stream containing audio data are to be recorded;
- and
- a video manager recording area located in a different position from the video data recording area in a direction of a diameter of the recording medium, in which control information is to be recorded,
- wherein the control information includes a mixed mode flag indicating whether at least two of multiplexed audio, multi-channel audio and monaural audio are mixed as one stream, and selected in succession.
A system for recording audio data on a disc-shaped recording medium comprising:
- a recording device which records video data and audio data in a video data recording area of the recording medium as an audio stream;
- and
- a generating device which generates control information including a mixed mode flag indicating whether at least two of multiplexed audio, multi-channel audio and monaural audio are mixed as one stream, and selected in succession,
- wherein the recording device records the control information in a video manager recording area located in a different position from the video data recording area in a direction of a diameter of the recording medium.
A system for reproducing audio data from a disc-shaped recording medium including a video data recording area in which video data and an audio stream containing the audio data are recorded, and a video manager recording area located in a different position from the video data recording area in a direction of a diameter of the recording medium in which control information is recorded, wherein the control information includes a mixed mode flag indicating whether at least two of multiplexed audio, multi-channel audio and monaural audio are mixed as one stream, and selected in succession, the system comprising:
- a reading device which reads the control information from the video manager recording area of the recording medium;
- and
- a controller which controls the reproduction of the audio data recorded in the video data recording area of the recording medium based on the control information.
A method of recording audio data on a disc-shaped recording medium comprising the steps of:
- recording video data and audio data of one audio stream in a video data recording area of the recording medium;
- generating control information including a mixed mode flag indicating whether at least two of multiplexed audio, multi-channel audio and monaural audio are mixed as one stream, and selected in succession;
- and
- recording the control information in a video manager recording area located in a different position from the video data recording area in a direction of a diameter of the recording medium.
A method of reproducing audio data from a disc-shaped recording medium including a video data recording area in which video data and an audio stream containing the audio data are recorded, and a video manager recording area located in a different position from the video data recording area in a direction of a diameter of the recording medium, in which control information is recorded, wherein the control information includes a mixed mode flag indicating whether at least two of multiplexed audio, multi-channel audio and monaural audio are mixed as one stream, and selected in succession, the method comprising the steps of:
- reading the control information from the video manager recording area of the recording medium;
- and
- controlling the reproduction of the audio data recorded in the video data recording area of the recording medium based on the control information.
